氧化铝厂中间降温设备配置方案分析及应用

Analysis and Application of Intermediate Cooling Equipment Configuration Scheme of Alumina Plant

通过换热器的换热计算,对Ⅰ、Ⅱ、Ⅲ组分解系统换热器使用情况进行了对比分析,结果表明:Ⅰ、Ⅱ系列宜选用螺旋板式换热器,其使用寿命可达3 a;Ⅲ系列宜选用立式宽流道板式,通过优化配置后分解系统换热器运行情况统计表可知,其换热量可达4600 kW以上。

Application of heat exchanger ofⅠ,Ⅱ,Ⅲgroup's decomposition system is compared and analyzed through heat exchange calculation of heat exchanger,the results show:Ⅰ,Ⅱseries is proper to select a spiral plate heat exchanger,its service time can reach 3 years;ⅠⅡseries is proper to select a vertical wide-runner plate heat exchanger,we can know the heat exchange amount can reach more than 4600 kW through heat exchanger operation statistics after optimizing configuration.
